To aZZ whom it may concern.-

Be it known that I, EDWIN M. KELLOGG, a citizen of the United States, now residing at Chicago, in the county of Cook and State of Illinois, but formerly at VVaupun, in the county of Fond du Lac and State of WVisconsin, have invented certain newand useful Improvements in Grain-Binders, of which the following is a specification.

In grain-binders generally in use now-adays the arrangement and construction of the knotting and holding devices are such that at the end of the tying operation there is considerable slack left in the band between the straw and the knot,which must be taken up by the expansion of the sheaf, and part of the benefit of the compression to which the gavel is subjected in the machine is therefore lost, sometimes to such a degree as to endanger the security of the band.

My present object is to bring the tying and holding devices into such close proximity to the gavel and to each other, and to arrange and control them in such manner that the knot may be formed practically in contact with the straw, so as to leave no appreciable slack in 'the band and prevent any ensuing expansion of the sheaf; and to this end myinvention consists in combining with the breastplate and with the tying-bill a cord-holder having a fixed relation to said brcastplate and tying-bill, and consisting of a notched flange-disk, much resembling a crown-wheel, and therefore sometimes hereinafter termed a crown-disk, havingits facein close proximity to the inner side of the breast-plate and its flange turned away therefrom, and a shoe saddling thefiange of this disk between it and the knotter and in such position that the nose of the knotter sweeps close thereto as it gathers and grasps the crossed ends of the band; in combining with the crown-disk and the shoe which saddles its flange means whereby a relative yielding of one away from the other is permitted to ease the stress upon the cord; in combining with the crown-disk and the shoe which saddles its flange a spindle secured to the disk and whereby it is turned, bearings in which said spindle may slide, and a spring acting upon said spindle to hold the disk against the shoe; .in combining with the position.

crown-disk and its yielding spindle a polygonal delay-sleeve pinned to said spindle, and a delay-flange on the face of the driving-wheel or tyer-cam, whereby any given face of said sleeve will remain in engagement with the flange, notwithstanding the yielding of the disk and spindle; in combining with a tyingbill and flanged holder-disk a shoe saddling said flange, a gear and cam wheel by which the bill and disk are driven, a knife affixed to a shank or plunger which slides in hearings in the stock or bracket that supports the tyer, knotter,and holder, and a camway or track in the face of the gear and cam-wheel, by which said plunger is depressed to carry the knife downward past the shoe and between it and the bill, and in various other combinations and details of construction hereinafter described and claimed.

In the drawings, Figure 1 is an elevation, assumed to be taken from the front of a righthand machine, of so much of a grain-binder embodying my invention as is necessary to an understanding thereof. Fig. 2 is a plan view or top view of the cord-holder and its spindle with driving-pinion and delay-sleeve or shoe-sleeve, Fig. 3,an elevation from the inner side of the mechanism embraced in the first figure, with the gear and cam wheel by which the parts are immediately actuated shown in section, and the tying-bill indicated only in dotted lines; Fig. 4, an elevation of said gear and cam wheel from the front side, showing the shank of the knife and explaining the manner in which it is operated from said wheel, and Fig. 5 a section through the cord-holder and holder-shoe A is the gear and cam wheel by which the knotter is driven and theliolder actuated and controlled, now often termed the tyer-cam. This is mounted upon and turned by the usual driving-shaft, sometimes called the tyershaft, A, and is constructed with the ordinary gear-segment, a, and delayledge a, for rotating the knotter-spindle and locking it in It also has another and inner concentric delay-ledge, a", cut away at apoint, a", to leave a gap, and a single or solitary tooth, at, opposite said gap, to act in connection with a delay-sleeve and pinion upon the holderspindle in order to alternately lock it and impart a forward movement the distance of a single notch with each revolution of the tyer cam, as will presently appear.

A bracket or stock, 13, is sleeved upon the tyer-shaft, and depending therefrom has its feet bolted to and supporting the breastplate B, which is here indicated as overhanging the passage-way for the grainthe usual position in machines of the prevailing type. Bearings I) b on the inner side of the bracket receive the spindle c of theknotter or tying-bill O, and between these hearings the spindle carries a pinion, c, and a delay-shoe, 0, arranged to respectively engage with the gearsegment and with the outer delay-ledge on the tyer-ca'm, so that the knotter may receive a single revolution at the proper time, and then be locked in position during the rest of the revolution of the cam. This knotter does not differ or need not difif'er from those now in use, being composed simply of an outer jaw rigid with the spindle and a pivoted inner jaw having a roller on its heel extremity controlled by cams, so that it shall open and close as required in the operation of tying the knot.

The outer side of the bracket or tyer-stock is provided with bearings (Z d d, parallel with those in which the knotter-spindleis mounted, and in these bearings is mounted the holderspindle D, having affixed to its upper end, in position to engage with the inner delay-ledge of the tye'r-cam, a polygonal sleeve, E, formed with equal faces parallel to the axis of the spindle and of considerable length, each face affording a delay-shoe, and the number of faces corresponding to the number of notches in the holder'disk, so that each notch in succession may be brought into action and retained in position to hold the cord-strands stationary. Below the sleeve is a pinion, E, keyed to the spindle and having as many inter-dental spaces as there are delay faces or shoes upon the sleeve and notches in the disk, and this is operated by engagement withthe solitary tooth once in the revolution of the tyer-cam, and when the delay-sleeve is opposite the gap in the ledge, to turn the spindle the distance of one notch in the disk, bringing the next delay-face of the sleeve in engagement with the delay-ledge at the end of the turning movement, which is just sufficient to carry the cordstrands beneath the holder-shoe to the point where they are to remain stationary until severed.

The holder-spindle extends downward from the pinion thereon until it nearly touches the breast-plate, and upon its lower end is fixed the holder wheel or disk F, consisting of a circular plate, f, lying close to and parallel with the inner face of the breast-plate, and of such diameter as to revolve with its periplr cry in close proximity to the knotter or tying-bill. This periphery has an upset-ting flange or rim projecting parallel with the knotter-spindle, and a suitable number of notches,f, are cut in the flange at equal distances apart for receiving the cord from the binder-arm, giving to the disk the general appearance of a crown-wheel. This resemblance will be further increased if the rim is formed, as it may be, of a series of independent teeth projecting from the periphery of the disk at the properrangle andv adapted to receive the cord in the interdental spaces. Bolted to the stock or bracket is the shank of a shoe, G, grooved in the segment of a circle to saddle the rim of the disk and embrace its side walls at the point nearest the knotter, the groove being of such depth that the depending ribs of the shoe may come close to the body of the disk and to or beyond the bottom of the notches, that the cord may be properly clamped. The inner side ofthe shoe is so closeto the knotter that it is touched or nearly touched by the nose thereof when in its revolution it reaches a position to pass the end strands of the cord clamped therein, or when it is pointing directly out toward the holder. In order that the holder may grasp the cord elastically, so as to compensate for the lumps, inequalities, or imperfections, it is necessary that one of the clamping-surfaces should yield from the other against spring-pressure, and as the holder-shoe serves to direct and position the cord-strands, so that they may be received between the open jaws of the knotter as it comes around, it follows that the yielding should take place in the disk. This I accomplish by means of a coiled spring, H, surrounding the holder'spindle between its lower and central bearings, seated atone end against said lower bearings and at the other pressing upon a collar, h, carried by the spindle, so as to draw the disk up against the shoe. Since the tension of the spring may require to be increased or decreased, the collar is made as an adjustable nut, taken upon screw-threads cut in the spindle, so that it may be turned down to compress the spring, or up to allow it to expand, thus increasing or decreasing the holding or compressing force. In the yielding movement thus permitted the delay sleeve will remain in engagement with its ledge on the tyer-cam, owing to its length and to its faces being parallel with the spindle.

The delay-ledges, segment-rack, and single tooth upon the face of the tyer-cam are of course so arranged and timed relatively to the holder and knotter-spindles and the pinions and delay-shoes thereon as to insure the tying and grasping movement coming in proper order or unison, and the tyer-shaft, which carries the cam, is also so timed relatively to the other mechanism of the binder attachment as to insure these operations following the appropriate movement of the hinder-arm. Thus it will be seen that the cord will be laid by the binder-arm in one of the notches of the crown-disk as the arm finishes its movement to cut off and encircle the gavel, and this notch will be the one at the moment just in advance of the shoe. The ensuing fractional rotation of the disk will carry the cord under the shoe and firmly clamp it. Then ICC after the knot has been tied and the band ends severed, and as the binder-arm recedes the spool-strand or' ball-strand will be laid in the next notch, which has now been brought ried by the disk under the shoe and clamped between the two will be caused to follow the lines of the lower inner edge of the shoe, and is thus guided and carried toward and across the head of the knotter, bringing the strands into the best possible position to enter between the open tying'jaws when they come around after winding theloop. After these end strands have been received between the jaws and been grasped by their closure, and when the loop -has been pulled or stripped off upon them,

they are to be severed between the knotter and holder, so that the bound sheaf may be ejected from the machine and the knot tightened as it is passed from the tying-jaws.

; s No particular form of knife or cutter is absolutely essential to the purpose just stated; but th at which Ihavedevised and consider most simple and effectivein this arrangement is as follows: Bearings 43 project from the stock toward the rear face of the tyer-cani and receive a rod or plunger, I, parallel or nearly parallel to the knotter'spindle and having at its upper end an anti-friction wheel, i, which enters a camway or track, 1, formed in sald rear face.

-This track is concentric with the axis of the cord-strands are carried by each successive movement of the holder-disk, preparatory to the completion of the knot, and in the downward movement of the plunger this knife is carried against said strands and severs them.

The plunger, constituting the shank of the knife, is formed in two sections, the upper of which has a threaded socket,into which takes the serew-threaded stem of the lower section bearing the knife, so that as the knife becomes worn the plunger can be lengthened by unscrewing the lower section, carrying the blade to a correspondinglylower point. Ajam-nut, i", will be placed upon the lower section,so as to cramp that against the upper after adj ustment and lock the parts in their adjusted position.

In operation the movement of the holder, taking place of course after the binder-arm has come around.

laid the strands of cord in the proper notch, will commence concurrently or about concurrently with the revolution of theknotter, and since the'knotter-jaws at the outset turn away from the holder the cord, as itis carried beneath the shoe, will be taken in a direction to meet them as they come around again in their revolution-that is, it will be carried transversely tothe axis of and past the knotterspindle-so that the jaws may be open at about the end of the third quarter of their revolution to receive the strands. Thereafterthey will immediately close, grasp them, and, reaching the end oftheir revolution, will come to a stop. Then the knife descends and severs the strands close to the shoe, leaving the portion of the last strand laid running from the shoe to the point of the binder-arm and thence to the receptacle still clamped,to be retained until the next binding operation.

I am aware that it has been customary to apply a springpressed shoe to the ordinary flat notched holder-disk heretofore used in grain-binders, and to make the stress of the spring adjustable. In such structure, however, the edge of the shoe adjacent to the knotter does not serve as a definite guide for the purpose of leading the cord ends to a position where they will enter between the open jaws of the knotter; therefore the fact that the disk remains relatively stationary while the sadd'ling-shoe yields does not contribute to any function except that of mere clamping, while in my device, on the contrary, the yielding of the crown-disk while the shoe remains stationary enables the shoe,.by its inner lower edge, to act as a guide to absolutely direct the end strands between the open jaws as they I am also aware that Letters Patent No. 242,021 were granted to John 1. Monroe, May 24, 1881, describing a holder consisting practicall y of a flat notched plate and a revolving notched disk which yields away from the plate, and between which and the contiguous surface of the plate the strands are intended to be clamped. In practice it is apparent that should any lump or enlargement of the cord cause the disk to yield the grasp upon the whole length of the strands lying between the two clamping-surfaces will be relaxed, except at the point where such lump or enlargement comes, and this will constitute the sole resistance to the strands. Therefore if one strand is uniformly smaller than the largest part of the other in the length between the clampingsurfaces it must be released or relaxed; but it will be observed that in my device the yielding of the disk does not change the spaces between the inner side walls of the shoe and the exterior walls ofthe rim, though it may change thelength of cord grasped within such. spaces. The, strands will therefore continue to be clampedbetween said walls with equal force. Again, in Monroes device, the fact that the clamping-plate remains stationary while the holder yields does not contribute to any function served by the plate as a guide to direct the end strands between the knotting-jaws, while in mine, as already pointed out, the yielding of the disk while the shoe remains stationary does enable the shoe, by its inner lower edge, to act as such guide, notwithstanding any yielding of the opposing clamp.
